Question about 2007 Mercedes-Benz ML320 CDI
My car won't start and someone told me to test if the starter is getting juice when I turn the switch. ( 2000 ml320 ) Thanks
If you have a test light and a helper it is quite easy. Clip the test light to a good ground and with the probe end touch the large post on the starter. The light should light as this is the positive battery cable from the battery. Now touch the small post, there should not be anything there, have your helper turn the ignition to the crank position and the light should light while you are still touching the small post. This will tell you that everything is working as it should and that your starter is not working properly. If you remove it and take it to the parts store they will be able to hook it up to a test machine and confirm that it is bad, but you just did that. Either way, you will have your core in hand and not have to worry about paying a core charge and then returning to the store when you are finished with the job.

Crank shaft position sensor is bad. This is the most common failure. Its location is on the rear drivers side of engine, where the transmission bell housing mates to the engine, only one small bolt and a two prong electrical connector hold it on. Usually will not throw a trouble code. If you remove it you can test it with an ohm meter, will have an erratic reading or read open loop, can malfunction intermittently or permanently after parking vehicle and won't restart. Applying some heat source to it during ohm testing with a hot air heat gun will usually cause the sensor to read open loop if your not sure if its bad or not. This reply is probably way to late, but I just happened to come accross it while online. Harry (master certified MBZ diagnostic tech)

Did you try jacking up the car at the front then wiggle the steering as you turn the key? Did you try a spare key? Spray inside the mechanism with WD40. Try putting the key in at different depths and turning.
The lock cylinder is a replace only item.
